Most of the QDSS driver is just a hack to map pages, anyway.  Someone
needs to take a look at the R6 server and fold the R5 QDSS module back
into it, removing all the wierd ioctl()'s having to do with memory
mapping.  Then the QDSS driver needs to be hacked down to the point
where it's just handing the pmap() entry points and the mouse I/O.
